Understanding Rent Increase Laws in Ireland

Tenancy Types & Agreements published July 05, 2025

Renting a home in Ireland comes with various responsibilities and protections under the Residential Tenancies Act 2004. Whether you're facing a rent increase or need advice, understanding your rights is critical for a smooth renting experience.

Rent Increase Protocols

In Ireland, landlords must adhere to specific legal processes when increasing rent. According to the Housing (Standards for Rented Houses) Regulations 2019, tenants are protected under a clear framework for rent adjustments. Here’s what you need to know:

Notice Requirements

Your landlord must provide at least 90 days' written notice before a rent increase takes effect. This notice must state:

  • The new rent amount
  • The date from which the new amount applies
  • A statement confirming the rent complies with market rent and local values
Make sure the notice is delivered in writing by your landlord to ensure adherence to legal standards.

Frequency of Rent Increases

Under the Residential Tenancies Act, rent reviews can typically only occur once a year, ensuring stability for tenants. However, exceptions may apply in Rent Pressure Zones (RPZs), where specific adjustments might differ based on local regulations.

Disputing a Rent Increase

If you believe a rent increase is unjustified, the Residential Tenancies Board (RTB) provides avenues to dispute it. You must act quickly:

  1. Check that the notice complies with legal standards.
  2. File a complaint with the RTB if necessary.

Forms such as the RTB1 can be submitted to initiate a review process. You can find details and the form on the RTB website.

Your Rights as a Tenant

Being informed about your tenant rights can help you navigate rental agreements effectively.

  • Protection Against Unfair Evictions: Eviction can only occur under specific legally compliant conditions.
  • Right to Repair: If your rented property needs urgent repairs, the landlord is obligated to address them promptly.
Always document communications and maintain records to ensure transparency and protection of your rights as a renter.
  1. What should I do if I receive a rent increase notice? Review the notice for compliance with legal requirements. It should provide a 90-day warning, state the new rent, effective date, and confirm market-value compliance.
  2. How often can my rent be raised? In most cases, rent can only be increased once every 12 months. Exemptions may apply in designated Rent Pressure Zones.
  3. Can I dispute a rent increase notice? Yes, file a complaint with the RTB within the stipulated time if the increase is unjustified or the notice is non-compliant.
  1. How to contest a rent increase?
    1. Step 1: Review the notice for legal compliance.
